(UFPB-OP714). Diagnosis: Similar to A. hehu by the presence of two ventral rows of tubercles in tibia IV. It can be distinguished from A. hehu and A. parvus due to the presence of one large, dorso-ectal, apical tubercle and one ventro-ectal, apical tubercle on its patella. It differs from A. hehu, A. leonidas, and A. parvus in having an undivided area II. It differs from A. tepui and A. leonidas in having a row of granules on the lateral margins of its dorsal scutum. Etymology: “ quilombola ” is a Brazilian Portuguese name for a person who lives in a quilombo, a settlement inhabited by black slaves after they escaped from their exploitative landlords where their descendants continue to live. Q uilombos are a symbol of black resistance. The fungus-harvestmen interactions were observed at the Quilombo Nazaré. quilombola is used here as an indeclinable noun in apposition.

Some wasp species use spiders as food resources, overcoming several anti-predator barriers that are exerted by spiders. Tromatobia ichneumonid wasps are spider egg predators that usually attack Araneidae species, although there are few records of predation on Clubionidae, Philodromidae, Linyphiidae, Tetragnathidae, and Theridiidae spiders. Here, we describe the interaction between Tromatobia sp. and Chrysso compressa, a subsocial theridiid spider that exhibits extended maternal care, in the Atlantic Forest of southeastern Brazil. We observed that the larva of Tromatobia sp. develop inside the egg sacs of C. compressa, preying on the entire egg mass and building cocoons that change the color and morphology of the egg sacs. Despite these structural modifications, we registered an adult female of C. compressa guarding and caring for the cocoons (attacked egg sac) of the predators as if they were offspring (non-attacked egg sac). To the best of our knowledge, this study represents the first record of Tromatobia preying on Chrysso eggs. [ABSTRACT FROM AUTHOR]

Borboleta - Abstract
Orientador: Keith Spalding Brown Junior Dissertação (mestrado) - Universidade Estadual de Campinas, Instituto de Biologia Resumo: Estudou-se a dinâmica populacional dos adultos de cinco espécies de Ithomiinae residentes no Horto Florestal de Sumaré, Estado de São Paulo (¿22 GRAUS¿ 49¿ Sul e '$7 GRAUS¿ 17¿ Oeste) que constitui uma formação vegetal produzida pelo homem. As estimativas dos tamanhos populacionais destas borboletas, pelo método de captura-marcação-recaptura, foram feitas pelo índice de Lincoln-Petersen e pelo Método de Jolly-Seber. As populações de Mechanitis polymnia, Mechanitis lysimnia e Hypothyris ninonia apresentam dinâmicas populacionais bastante semelhantes. Reproduzem-se e crescem durante a estação chuvosa, reduzindo e / ou interrompendo seus períodos reprodutivos durante o inverno seco, época em que estas espécies miméticas coloridas se concentram em bolsões, atingindo os maiores níveis populacionais. A população de Dircenna dero é pequena e bastante móvel, não se concentrando em bolsões. Esta espécie se reproduz principalmente nas áreas mais abertas do Horto Florestal, durante o outono e o inverno. A quinta espécie de Ithomiinae, Mcclungia salonina, vive restrita nas áreas do bolsão. Sua dinâmica populacional é bastante diferente das outras espécies. Este ithomiíneo se reproduz principalmente no verão e no início do outono, atingindo os maiores níveis populacionais em maio. A partir deste período a população decresce a níveis muito baixos, permanecendo assim durante o inverno e a primavera... Observação: O resumo, na íntegra, poderá ser visualizado no texto completo da tese digital Abstract: A study was made on the adult population dynamics of five species of ithomiine butterflies present at the Sumaré Forestry Station (Horto Florestal de Sumaré), state of São Paulo, Brazil (¿22 GRAUS¿ 49¿ S, ¿47 GRAUS¿ 17¿ W) in modified vegetation. Estimates of population parameters were obtained through mark and recapture data using the Lincoln-Petersen index and the Jolly-Seber Method. Population of Mechanitis polymnia, Mechanitis lysimnia and Hypothyris ninonia demonstrated very similar seasonal patterns in their population dynamics. Populations reproduce and grow during the rainy season, this being interrupted during the dray winter months when these brightly colored mimetic species aggregate in ¿pochets¿ and reach their largest population sizes. In constrast, Dircenna dero disperses greatly, has small population sizes and does not concentrate in dry-season aggregations. This species reproduces principally in open areas of the Horto Florestal during the fall and winter. The population of the fifth ithomiine species, Mcclungia salonina, is restricted to the moist woods where Mechanitis and Hypothyris form their winter aggregations. Its population dynamics differs considerably from that of the other species. The population builds up during summer and the beginning of fall reaching its greatest density in May. After this time, the population falls to very low levels which are maintained during the winter and spring...

Objective: To report the influence of heavy metals in the onset of cancer, thus describing the main metals that hold this possibility, also citing the types of cancers commonly caused by exposure to these metals. Methodology: This is a literature review of a descriptive and qualitative nature about the influence of heavy metals on cancer. The study was carried out from December 2020 to February 2021, by analyzing the databases: Pubmed, SciELO and Lilacs. The search and selection of materials were carried out based on previously established inclusion and exclusion criteria, which totaled 48 materials, these published between the years 2000 to 2021, thus composing the present study. Results and discussion: Even in low concentrations, exacerbated exposure to heavy metals promotes chronic inflammation, which triggers oxidative stress, and subsequently the process of carcinogenesis. Among the main metals involved in the carcinogenesis process, we can mention: copper, mercury, cobalt, nickel, cadmium, chromium, arsenic, silver and lead. Regarding the types of cancers affected by continued exposure to these metals, there are: lung, skin, ovary, breast, stomach, prostate, brain and larynx cancers. Conclusion: Heavy metals have a great influence on the process of carcinogenesis, which is intrinsically linked to sequenced exposure and bioaccumulation of these elements. Numerous are heavy metals with the potential to trigger the development of cancers, which reflects in the variability of tissues and organs affected and the diversity of tumors in humans. Objetivo: Informar la influencia de los metales pesados en la aparición del cáncer, describiendo así los principales metales que tienen esta posibilidad, citando también los tipos de cánceres comúnmente causados por la exposición a estos metales. Metodología: se trata de una revisión de la literatura de carácter descriptivo y cualitativo sobre la influencia de los metales pesados en el cáncer. El estudio se realizó de diciembre de 2020 a febrero de 2021, mediante el análisis de las bases de datos: Pubmed, SciELO y Lilacs. La búsqueda y selección de materiales se realizó en base a criterios de inclusión y exclusión previamente establecidos, los cuales totalizaron 48 materiales, estos publicados entre los años 2000 a 2021, componiendo así el presente estudio. Resultados y discusión: Incluso en concentraciones bajas, la exposición exacerbada a metales pesados promueve la inflamación crónica, que desencadena el estrés oxidativo y, posteriormente, el proceso de carcinogénesis. Entre los principales metales involucrados en el proceso de carcinogénesis, podemos mencionar: cobre, mercurio, cobalto, níquel, cadmio, cromo, arsénico, plata y plomo. En cuanto a los tipos de cánceres afectados por la exposición continua a estos metales, se encuentran: cánceres de pulmón, piel, ovario, mama, estómago, próstata, cerebro y laringe. Conclusión: Los metales pesados tienen una gran influencia en el proceso de carcinogénesis, que está intrínsecamente ligado a la exposición secuenciada y bioacumulación de estos elementos. Numerosos son los metales pesados con el potencial de desencadenar el desarrollo de cánceres, lo que se refleja en la variabilidad de los tejidos y órganos afectados y la diversidad de tumores en los seres humanos. Objetivo: Relatar a influência dos metais pesados no acometimento do câncer, descrevendo assim, os principais metais detentores dessa possibilidade, citando ainda, os tipos de cânceres comumente ocasionados pela exposição a esses metais. Metodologia: Trata-se de uma revisão da literatura de natureza descritiva e qualitativa acerca da influência dos metais pesados no acometimento do câncer. O estudo foi realizado no período de dezembro de 2020 a fevereiro de 2021, mediante análise nas bases de dados: Pubmed, SciELO e Lilacs. A busca e seleção dos materiais foram realizadas baseando-se em critérios de inclusão e exclusão previamente estabelecidos, o que totalizou 48 materiais, estes publicados entre os anos de 2000 a 2021, compondo assim o presente estudo. Resultados e discussão: Mesmo em baixas concentrações, a exposição exacerbada aos metais pesados promove inflamação crônica, o que desencadeia o estresse oxidativo, e subsequentemente, o processo de carcinogênese. Dentre os principais metais envolvidos no processo de carcinogênese, pode-se citar: o cobre, mercúrio, cobalto, níquel, cádmio, cromo, arsênio, prata e o chumbo. No que se remete aos tipos de cânceres acometidos pela exposição continuada a esses metais, tem-se: os cânceres de pulmão, pele, ovário, mama, estômago, próstata, cérebro e laringe. Conclusão: Os metais pesados apresentam grande influência no processo de carcinogênese, o que está intrinsicamente vinculado a exposição sequenciada e bioacumulação destes elementos. Numerosos são os metais pesados com o potencial de desencadear o desenvolvimento de canceres, o que reflete na variabilidade de tecidos e órgãos afetados e a diversidade de tumores aos seres humanos.

Introdution: The new coronavirus is called SARS-CoV-2, however it causes Severe Acute Respiratory Syndrome (SARS). This virus is easily transmitted from person to person through contact with contaminated surfaces, as well as through aerosols, this according to the World Health Organization (WHO), but it is non-definitive evidence, and which is likely to be more propitious in places with poor ventilation and crowding. It results from symptoms such as: fever, cough, fatigue, dyspnoea, loss of smell and taste; and less frequent headache, throat and diarrhea. Objective: to analyze the association between worsening comorbidities, age and SARS-CoV-2 infection. Methodology: this research is of qualitative / quantitative property, with an exploratory and descriptive attribute, fostered through secondary data extracted from scientific articles from indexing sources, in the year 2016, 2018 and 2020, with language: English, Spanish and Portuguese. Results: it aims to understand the disease through statistical data through the amount of death by COVID-19, age group, the most prominent comorbidity, the most notified sex, and comparisons between deaths in Brazil due to neoplasms (breast, prostate) and deaths from cardiomyopathies, diabetes, obesity, COVID-19 and unspecified SRAG. Final considerations: Therefore, the best ways to prevent this pathology is social isolation, and to avoid possible agglomerations, since the gradual growth of deaths by COVID-19 has a great relationship both with the present comorbidities and with advanced age, therefore, people at risk should redouble their care. Introducción: El nuevo coronavirus se llama SARS-CoV-2, sin embargo, causa el síndrome respiratorio agudo severo (SARS). Este virus se transmite fácilmente de persona a persona a través del contacto con superficies contaminadas, así como a través de aerosoles, según la Organización Mundial de la Salud (OMS), pero es una evidencia no definitiva, y es probable que sea más propicio en lugares con mala ventilación y hacinamiento. Es el resultado de síntomas como: fiebre, tos, fatiga, disnea, pérdida del olfato y del gusto; y dolor de cabeza, garganta y diarrea menos frecuentes. Objetivo: analizar la asociación entre el empeoramiento de las comorbilidades, la edad y la infección por SARS-CoV-2. Metodología: esta investigación es de propiedad cualitativa / cuantitativa, con atributo exploratorio y descriptivo, fomentada a través de datos secundarios extraídos de artículos científicos de fuentes de indexación, en los años 2016, 2018 y 2020, con idioma: inglês, español y portugués. Resultados: tiene como objetivo comprender la enfermedad a través de datos estadísticos a través de la cantidad de muertes por COVID-19, grupo de edad, la comorbilidad más destacada, el sexo más notificado y las comparaciones entre muertes en Brasil por neoplasias (mama, próstata) y muertes por miocardiopatías, diabetes, obesidad, COVID-19 y SRAG no especificado. Consideraciones finales: Por tanto, la mejor forma de prevenir esta patología es el aislamiento social, y evitar posibles aglomeraciones, ya que el crecimiento paulatino de las muertes por COVID-19 tiene una gran relación tanto con las comorbilidades actuales como con la edad avanzada, por tanto, las personas en riesgo deben redoblar su atención. Introdução: O novo coronavírus é chamado de SARS-CoV-2, contudo causa a Síndrome Respiratória Aguda Grave (SRAG). Este vírus é transmitido facilmente de pessoa para pessoa por meio de contato com superfícies contaminadas, como também por meio de aerossóis, isso de acordo com a Organização Mundial da Saúde (OMS), mas são evidências não definitivas, e que provavelmente sejam mais propícias em locais com pouca ventilação e aglomeração. Decorre de sintomas como: febre, tosse, fadiga, dispneia, perda de olfato e paladar; e menos frequente dor de cabeça, garganta e diarreia. Objetivo: analisar a associação entre agravamento das comorbidades, idade e infecção por SARS-CoV-2. Metodologia: esta pesquisa é de propriedade qualitativa/quantitativa, de atributo exploratório e descritivo, fomentados por meio de dados secundários extraídos de artigos científicos de fontes de indexação, no ano de 2016, 2018 e 2020, dispostos de idioma: inglês, espanhol e português. Resultados: possui o intuito de compreender a doença através de dados estatísticos por meio da quantidade de óbitos por COVID-19, faixa etária, a comorbidade que mais se sobressai, o sexo mais notificado, e comparações entre os óbitos no Brasil por neoplasias (mama, próstata) e óbitos por cardiomiopatias, diabetes, obesidade, COVID-19 e SRAG-não especificada. Considerações finais: Portanto, as melhores formas de se precaver desta patologia é o isolamento social, e evitar possíveis aglomerações, já que o crescimento gradativo de óbitos pela COVID-19 possui grande relação tanto com as comorbidades presentes, como com a idade avançada, por isso, pessoas de risco devem redobrar os seus cuidados.

Coronaviruses are viruses with simple RNA, whose family can be subdivided into alpha, beta, gamma and delta-coronavirus, which result in infectivity in animals and humans. SARS-CoV-2 has several mechanisms that contribute to its entry and pathogenicity in humans, using the S glycoprotein, which binds to ECA II in the host cell and uses it as an apparatus for replication, as an aid. This paper aims to describe characteristics and comparability between coronaviruses, reports on their virulence factor, clinical data presented by the infected, as well as the main forms of diagnosis, emphasis on molecular tests and the collaboration of imaging for a better prognosis, in addition to citing important intervention measures and describe the importance of these interventions under the large number of cases. This study is a literature review, in which articles indexed in the databases were selected: Pubmed, Scielo and Lilacs, using the terms as descriptors: Coronavirus infections; Covid-19; Virology; Diagnostic Imaging. Where, after content analysis proposed by Bardin (2008) and Minayo (2001) and selection, a total of 37 articles were elected, between the years 2019 and 2020. In conclusion, studies have shown the effectiveness of including intervention measures in combating the new Coronavirus, as well as in other respiratory transmission pathologies. RT-PCR is a very sensitive laboratory technique, which is used for viral detection. The use of imaging tests has contributed to greater reliability in the results.

Craspedisia cornuta resemble C. spatulata from Dominican Republic, but can be distinguished by embolus rectangular and shorter and smallest conductor while in C. spatulata the embolar base is rounded; embolus longer and largest conductor (see Levi, 1963, fig. 33; Fig. 4 C���H). If compared with the Chinese Craspedisia longioembolia, the proboscis in this species is very short and the distal area of embolus long and filiform (see Yin et al., 2003, figs 2���3, 5). The females of both other species, C. spatulata and C. longioembolia are unknown. Description. Male (IBSP 215592).

Trichobothria with rounded base, circular aperture and long hair (Fig. 6A), distributed in the leg as in male (Fig. 6 A���B); tarsal organ capsuled, smooth with circular aperture (Fig. 5H) and chemosensitive setae smooth and elongated (Fig. 6C). Abdomen with ventral plate lesser than male, circular anteriorly and having laterally with a group of hard spines, probably to rub in the stridulatory plate (Fig 7 A���C). Colulus oval and elongated at tip (Fig. 7D). Epigynum with ventral plate larger than long, subrectangular (Fig. 7E) or semicircular (Fig. 7F), with ample anterior opening. Internally with globose spermathecae, short copulatory ducts united at base, elongated fertilizations ducts and large inner area of the atrium (Fig. 8 A���B; see Levi, 1963, fig. 28). Natural History. Craspedisia cornuta individuals are found in tree trunks of Piptadenhia gonoacantha (Mart.) JF Macbr. (Fabaceae), Croton floribundus Spreng. (Euphorbiaceae), and Zanthoxylum rhoifolium Lam. (Rutaceae) in ranges ranging from 0.5m��� 1.7 m height (n = 55) in forest areas. Its distribution in the trunks is not random, occurring more frequently in places where there are shelter structures such as loose bark or protuberances and moss coverings along the trunk, which act as a rain protection roof (Fig. 9A, F). The webs are star shaped with anterior aperture (Fig. 9 B���D). The web is slightly inclined from the base towards the shelter (Fig. 2A). Craspedisia cornuta has nocturnal habits, remaining in this period in the trunk, outside the web. During the day, they are sheltered in the back part of the web (Fig. 9E). The webs are usually found in lichen and moss-lined trunks (Fig. 9). Adult individuals were found mainly in the summer, in the months of December and January (Fig. 10), a period of higher rainfall where lichens and mosses are lush. According to Paquin & Dup��rr�� (2001), the reproductive period of a spider species population is determined by the peak abundance of adult males. Thus we understand that the population of C. cornuta presents a spring and summer stenochronic phenological pattern with a very marked period of activity of adult spiders in a defined period of the year���according to the classifications of Tretzel (1954) and Paquin & Dup��rr�� (2001). This phenological pattern where sexually active males are available for a few months has also been recorded in other spider populations in the temperate (Merrett 1967) and Neotropical regions (Villanueva-Bonilla & Vasconcellos-Neto 2016; Villanueva-Bonilla et al. 2018). In the case of autumn 2016, some remaining adult females from the previous summer were still found (Fig. 10), probably individuals who had less pressure for predators or fluctuating climatic conditions in the region. One aspect that caught our eye when examining SEM images of the nails of the legs was the presence of a hardened substance covering the false claws and distal bristles to the legs. These characteristics were observed only in the legs III���IV of the females (Fig. 5 D���E), being absent in the legs I���II (Fig. 5F), as well as in the legs of the males where we did not observe these inlays (Fig. 2C). We suspect that the substance could be sap of lichens or mosses, where females usually build their refuges and remain largely hidden. Distribution.

Understanding high biodiverse areas and interactions among organisms requires reciprocal action between scientists and community through citizen science. This paper results from the joint efforts of an amateur nature photographer and scientists to describe the predation behaviour of the heron Ardea cocoi upon the lizard Ameiva ameiva. We also discuss the importance of citizen science and digital photography for natural history studies. [ABSTRACT FROM AUTHOR]

Deinopidae spiders are known mainly for their web-building behavior and prey-capture strategy. However, studies on their population ecology are scarce. Therefore, we evaluated the population fluctuation, phenology, and diet of Deinopis cf. cylindracea. We also investigated how abiotic (precipitation and temperature) and biotic (prey availability) factors influence the abundance of this species. Our results showed that D. cf. cylindracea has an annual cycle with a maximum density in March. The reproduction cycle occurs from March to July. The recruitment of spiders occurred between July and October, followed by a peak of young individuals in December, juveniles in February, subadults in April, and adults in May, indicating a 'fall stenochronous' phenological pattern. The climatic variables were important factors that influenced the fluctuation of the age of D. cf. cylindracea. Although we did not find a positive correlation between the climate and its abundance at time 0, we did observe a correlation with a delay of three months. The main preys were Formicidae and Coleoptera, and not all available preys were part of the spiders' diet. These results indicate that the spiders require time to respond to changes in environmental conditions and provide information about the different stages of development over time.

Received 18 May 2020, accepted 9 September 2020 Complex environments often have diverse animal communities. The structural complexity of plants has been directly and indirectly responsible for the abundance and diversity of spiders, allowing the establishment of different types of webs and influencing prey availability. Piptadenia gonoacantha and Croton floribundus trees are native species of the Atlantic Forest and have trunks with different structural complexities. The structural characteristics of the former vary according to the stem diameter, while the latter has a relatively simple trunk. This variation makes these plant species a good natural model for natural experiments designed to study how the structural components of trunks can affect the arthropod community, especially spiders. For this purpose, we sampled 30 trees of each species to determine their structural complexity and the abundance and richness of associated spiders. We classified the trees by level of complexity based on the abundance of their structural categories. As expected, the structural complexity of tree trunks explained almost 50% of the variation in species richness and abundance of spiders. Spider diversity, evaluated by the Shannon-Wiever index, was higher in trunks of P. gonoacantha included in the groups of higher complexity. This pattern however, was not observed in relatively simpler trunks of C. floribundus. On the other hand, the species-area relationship pattern was not supported by our data as we observed a nonlinear relationship between trunk surfaces and species richness. Differences in spider richness in the trunks appeared to be caused mainly by their specific microhabitat demands, which differed between groups according to their complexity. For some spiders, the overall trunk structure may play an essential role in the establishment of individuals. For others, specific structures such as loose bark or branches may be essential variables. [ABSTRACT FROM AUTHOR]

EGG cases (Zoology) ,SPIDERS ,MALES ,ORB weavers ,PATERNITY ,SPERM competition - Abstract
Certainty of paternity is considered an important condition for the evolution and maintenance of extended male care. In some species, males may cannibalize unrelated offspring or abandon the progeny when the uncertainty of paternity is high, or when they take over nest sites or females from other males. However, male protection of offspring can also evolve in situations of uncertainty of paternity, especially when males cannot recognize offspring relatedness. In such cases, males may take care of all their mate's offspring, regardless of paternity. In Manogea porracea (Araneidae), the only known spider species where males care for offspring, males repel competitors by assuming and defending specific positions within a female's web, but females accept multiple partners during the reproductive season. Consequently, males may care for some offspring produced with the sperm of their mate's previous partners. If males cannot detect offspring relatedness, we expect that they will not cannibalize progeny and will actively protect all offspring against predation. The main goal of this study was to investigate whether the extended male care depends on offspring relatedness recognition. Therefore, we experimentally manipulated offspring relatedness and the presence of foster males and two egg predators usually found invading M. porracea webs. We also compared our results with data from an experiment performed by Moura, Vasconcellos‐Neto, & Gonzaga (2017) using the same laboratory procedures, but introducing egg sacs fathered exclusively by the males. Males did not cannibalize offspring and protected the progeny against predation regardless of offspring relatedness. In addition, all males moved the egg sacs to the center of the web, remaining close to the progeny. We conclude that M. porracea males protect all progeny present in their partner's web and increase offspring survivorship regardless of relatedness. We discuss the behavioral and evolutionary implications of our findings, and potential triggers of male care in M. porracea. [ABSTRACT FROM AUTHOR]
